Answer:
the answer is 72.0 units:) thank me later!!!!!!!
PE stands for Potential Energy. It is the stored energy in an object due to its position with respect to some reference. It is expressed in Joules.
P.E = m * g * h OR P.E. = mgh
m - mass of the body
g - acceleration due to gravity
h - height attained due to the body's displacement.
K.E. stands for Kinetic Energy. It is the energy possessed by a body due to its motion.
K.E = 1/2 mv² where m = mass of the body; v = velocity with which the body is moving.
Answer:
.78 m/s north
Explanation:
Pls give brainliest if I correct
Answer:
0.5
Explanation:
The energy of a charged capacitor is given by 
where 
is the charge on it and 
is its capacitance. The capacitance is defined, geometrically, as
where 
is a constant that is determined by the material between the plates, 
is the area of the plates and 
is the distance between them. It is then that the capacitance is linearly inversely proportional to the separation distance; as the distance increases, the capacitance reduces.
Because it is linear, when the separation distance is doubled, other factors remaining constant, the capacitance is halved. Because the capacitance is halved, the energy is halved.
Let's see the mathematics.
Initial capacitance, 
at initial separation, 
If separation is doubled, separation becomes 
. Then the capacitance becomes
Initial energy, 
Final energy, 
Hence, 
Answer:
d. Relative humidity increases.
Explanation:
The expression of relative humidity in terms of absolute humidity, absolute pressure and saturation pression at measured temperature is:
When temperature decreases, the saturation pressure decreases also and, consequently, relative humidity increases. Therefore, the right answer is option D.
